WASHINGTON BAKER VANDERLIP, or sen DIEGO, cerrronura, assreiven FIVE ONEHUNDREDTHS T0 nn vnsr senses-mow, or new sonar,

To all whom it may concern Be it known that l, lNAsHINe'roN BAKERVANDERLIP, acitizen of the United States,

residing at San Diego, in the countyof San Diego and State ofCalifornia, havefinvented certain new and useful Improve ments inOre-Concentrators;and I do'hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to Which it appertains to make and use thesame.

My present invention relates to lIl'lpIOYG- merits in concentrators forores and the like, preferably, though not necessarily, of the .batea orcentripetal type wherein a circular vanning movement is imparted to theconcentrating table,fand wherein the discharge of the heavy concentratesis accelerated by. a suitable revolving Worm screw, and Wherein thisWorm screw may be driven at a vari able speed to conform to the desiredrate of delivery of the concentrates; and in vvhich the separation of,the concentrates from the gangue is accelerated by a series Of radialbattle plates mounted in'the bottom of the pan, and whereby also theradius of the circular movement of the pan may be adjusted withinlimits, so as to impart a variable lateral throw to the pan.

My invention will be more clearly understood after reference to theaccompanying drawings, which show the embodiment of the invention, andin Which like parts are indicated by siniilar reference symbolsthroughout the several views.

1 represents the outer Wall of the p which is attached to and moves withthe pan 2, which is in the form of an inverted frus tum of a cone,having the central opening Surrounding the exterior of this conicalportion 2 of the pan is a launder a forthe Fig. '3, as seen from thebottom of 5 is an end view as seenfroin the launder f gangue, in-theforin ofa circular trough which is l'JIOLCliflIlClSllflllOW as at 5, andnarrow and deep as at- 6, the narrow. and deep portions terminating inoutlets 7 which open into any suitable troughs or other conveyers, notshown,for carrying oif the gangue.

Mounted in the interior of the conical portion of the pan are a series.01 radial bafiie plates, preferably of difl'erentlengths and staggered,as shown at 9 and 10. These baille plates are secured ,to the bottom ofthe pan in any convenient way as by the flanges and bolts shown in Fig.l, and between these flanges, and next to the bottom of the pan,

the baffle plates are cut away to form elongated openings 11, see Fig.2. Thesebaflle platespreferably all terminate at substantially the Samedistance from the outer edge of the cone part of the'pan, but em nenendsof the baffle plates 9 project farther toward the opening e than do theshort F 2. In this. cylinder is mounted the WOTL'l'Il conveyer 14L,nounted on" the shaft 15 which is gournaled at one end in the botto n.of the cylinder 13, and at the other end in the bearing 17 supported bythe bracket 16,

"secured to the inside of thebcttom of the This cylinder 13 .has adelivery opening 13*,through Which theconcentrates fed by 'carriedv bythe supports 30. is journaled in "sleeves 31 carried by the theconveyer'le pass. The pan is given a vanning movement, as will behereinafter described, and to impartrotary motion to the'shaft 15 Iprovide a broken shaft, consisting vof-the universal joint 18, theshaftsegment 19, splined as at 19 to slide in the sleeve 20, connectedby the universal joint 20% to the segment 21, which'segmentcarries theWorm gear 22 meshing with the worm 23 on the shaft 2 which shaft carriesthe frictiQn. cone 25 Opposite this friction cone, and reverselydisposed, is a similar friction cone 26' mounted on the shaft 27carrying the beveled gear 28 meshing with the beveled gear 52 on themain drive shaft 51., 7

The shaft 27 is mounted inbearings 29 The shaft 24:

stems 32, adjustably mounted in the blocks 34-QBetween the bearings 31and blocks 34:

other I provide the springs 33, which tend to press "the cone 25 towardthe cone 26. These bearings 3d are carried bythe frame35. The stems 32may be adjusted by means of the adjusting screw bolts 36.

Passing between the two'c'ones is a belt or collar 37, of leather,reinforced rubber, or suitable material, which passes through theshifter 38 and feeding nuts 39 engaging the screw rod 40, having ahandle 41. The shifter slides freely on the rod 42,

and may be moved backward or forward along said rodby turning the handle41. The rod 42 is secured, at its opposite ends to the brackets 43 and14 carried by the frame 35, and the rod. 46 is journaled in said 7brackets.

it will be evident that by moving the collar 37 to the right or leftbetween the two friction (zones that the angular velocity of the cone25, relative to that of the cone 26, may be increased or decreased asdesired. In order to throw the cone 25 entirely out of; engagementwhendesired, I provlde a grooved collar 15, fastto the cone 25 and Theopposite pair of eccentrics 55 are driven by thebeveled gear 56 carriedby the shaft I 27, which beveled gear meshes with the beveled gear 57 onthe shaft 51*, at thetwo ends of which shaft are the beveled gears 52which mesh with the beveled gears 53 and drive the corresponding shaft 51 and eccentrics 55. These beveled gears are all arranged so that thevarious shafts 5 1 and the various eccentrics shall all have the sameangular velocity, and in order to get the properdirection of movement ofthe eccentrics on opposite sides of the pan, the beveled gear 53 shouldbe reversely disposed to the beveled gear 53 The eccentrics 55 may bepreferably of the well known type known as adjustable eccentrics, whoseeccentricity may be varied within limits, as desired, so that the throwof the eccentrics may be increased or decreased as desired. Theseeccentrics engage the cylindrical bearings 58 in the housing 59, seeFig. 2. Each eccentric 55 is provided with a stem 60 concentric with thebearing 58, and surrounding this stem are the end friction bearings 61.

Lubricant may be supplied through a suitable lubricator 62.

The housings 59 are rigidly attached to the under frame 63 carrying thepan. The shafts 55 supporting the pan are journaled in hollow columns61, secured together by suitable tie rods 65.

The ore for treatment is preferably provided to the pan by a feedingdevice which will evenly distribute the feed of the wet ore to the pan.Such an apparatus is shown in section in Fig. 2, in which representssupporting beams secured to any suitable framework, not shown, whichbeams support the trough or tank 71, provided with an opening 72 abovethe cylinder 73, which is supported from the tank 71 beneath which issuspended, as by means of the link 74, a cylindrical metal receptacle75, beneath which is suspended an inverted cup-shaped receptacle 76,having the flanged annular trough 7 7, which is substantially concentricwith the axis of the pan.

7 It will be obvious that if the ore in the usual semi-liquid state besupplied to the tank 71 it will flow through the opening 72 and into thereceptacle 75, and overflowing around the sides of this receptacle itwill flow into the annular trough 77, and from which it will flow in asubstantially uniform sheet into the pan at a suitable distance from theopening 3 therein.

The operation of the device is as fol.- lows Suppose all the parts ofthe machine to be in operation and the pan to be given the vanningmotion imparted to it by the eccentrics 55, the ore in the wet conditionas it comes from the stamp mills is fed into the tank 71, flowing downinto the receptacle 75, and it flows over the upper sides of saidreceptacle and into the annular trough 77, whence it is distributed inan even sheet onto the top of the ore already in the pan.
